San Francisco has hired engineering firm T.Y. Lin to help reduce the number of cracked eyebars on the Bay Bridge. Under the $1 million contract, Lin will design a system that could be installed in the event of another eyebar failure similar to those that occurred earlier this year. The firm will also design dampers to cut down on traffic vibrations on the bridge.

Compatible software programs and efficient partnerships with design-team architects, engineers and contractors are vital to the success of building information modeling, says James LeBer, an Ontario-based litigation specialist. The groups must clarify the allocation of risk and how a contractor might expose them to design liability. Walking through a BIM building model can highlight potential problems or deficiencies, LeBer says.

The Port Mann Bridge in British Columbia will be the widest bridge in Canada when completed in December 2012. The cable-stayed bridge will be 213 feet wide and consist of two five-lane decks separated by a median. T.Y. Lin International of San Francisco designed the $1.2 billion bridge.

Eyebars are in place in bridges all over California, despite their inherent structural flaws, engineers say. A cracked eyebar recently led to a serious accident on the San Francisco Bay Bridge. Under federal law, bridges designed with eyebars must be inspected every two years. However, some experts believe regulators should reconsider inspection intervals.
